TESTING-MACHINE.

Application filed April 13, 1909. Serial No. 489,620.

vention, such as will enable others skilled inty the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or ligures of reference markedthereon, which form a part of this specification.v

This invention relates to rail testing machines, and has for its objectto. improve the construction and operation of known machines of asimilar character.

To this end the invention consists of a support for carrying the carWheels and means for adjusting the supporting arm in a vertical arc, andmeans to permit the wheels to be swung at an angle or moved in ahorizontal arc with respect to the support, whereby the tread or flangeof the wheel may engage the rail under additional service conditions,which is not possible in existing machines.

The invention consists in details of construdtion and combination andarrangement of parts, as hereinafter more particularly set forth andthen specified in the claims.

In the accompanying drawings Figure 1 is a partial longitudinal sectionof a machine embodying my invention. Fig. 2 is a plan view of thesupporting arms. Fig. 3 is an end elevation of Fig. 2. Fig. l is adetail vertical section of a modified form of saddle-adjusting means.Fig. 5 illustrates lock ing keys having various degrees of osets. Fig. 6is a side elevation, partly in section, of a modification. Fig.l 7 is asimilar view of another modification, and Fig. 8 is a section on line8-8 of Fig. 7 showing one of the adjusting screws.

A designates one of the well known forms of metallic base or frame, andon which are supported, on blocks C or otherwise, the arcuate railsections 6 to be tested.

Mounted on a central shaft 13 Vis a hub 1, the outer periphery of whichhas concaved cylindrical or curved faces 2, and the inner ends of thearms are provided with convex curved faces to fit the faces 2. Said armsare held in place on the hubby keys 3 taking into recesses in both thearms and the hub, and bolts 4 pass through and connect the lugs 5 of theoppositely situated arms. In order to incline the arms I make use ofkeys 3a (Fig. 5) having various degrees of oii'set, each key 3a servingto produce either an upward or a downward inclination of the arm 16 inaccordance with the position in which the key 3a is inserted intherecesses in the hub and arm. If the keys 3a are inserted in the recessesshown in Fig. 1 in the position in which they are illustrated in Fig. 5,they will hold the arm inclined downwardly, but if these keys are turnedend for end, or reversed, they will incline the arm upwardly from thehub.

On the outer end of each arm 16 is provided a vertical cylindricalhousing 8, forming a bearing for a cylindrical boss 9 that forms a partof the wheel mounts. The boss is capable of being rotated in the housing8 and is held in its rotated position by means of bolts 11, passingthrough slotted lugs 12 on the arm 16, and a similar lug 15 on ahorizontal arm 10 of the wheel mount. After this adjustment keys 14 areinserted between the boss 9 and its housing 8 to prevent the boss 9from'rotating in said bearing. This adjustment permits the car wheel 17to b'e placed at an angle to the rail or skewed and held in such angularor skewed position. y

The saddles 44: of the auxiliary motors F are of coursel rotatable tothe same degree as the wheel axle mounts, and are held in their rot-atedposition by bolts 18 passing through slots 19 at the sides of thesaddle.

In Fig. 6 is illustrated a modification of the above-described means foradjusting the incline of the wheel axle mount during the operation ofthemachine, and to this end I provide on the arm 16 a depending bearing 21in which is mounted a short shaft 22 having on one end a sprocket orescapement wheel 23 and on the other end a pinion 24. The pinion 24:meshes with a rack 25 on the horizontal arm 10 of the wheel mount.

Pivotally connected at 26 to one of the struts 7 of the bed is a lever27 pivotally connected at 28 to a draw' rod 29 having notches a, Z) ando therein, said rod passing through a slot '30 in the bed A and providedwith a handle 31. The lever 27 has two escapement teeth or ngers 32, 33,one of which is below the sprocket wheel 23 and the other above. Vhilethe draw rod 29 is in the position shown in Fig. 6, and the notch Z)engages the frame A, the lever 2T is in nent-ral or inoperativeposition; by lifting' the draw-rod 29 and pulling it outward so that thenotch a` engages the bed the lower finger or tooth 32 is brought intothe path of the sprocket wheel 23, and at each revolution of the arm 16a tooth of the sprocket wheel 23 strikes the finger or projection 32,thereby moving said sprocket wheel one tooth, and the arm 10 of thewheel axle mount is moved, through the medium of shaft 22, gear 24 andrack 25 in one direction. By lifting the end 81 and shoving itinward sothat the notch c engages the bed A, the upper finger 33 is brought intothe path of the sprocket wheel 23 and the lower finger 32 simultaneouslymoved out of its path, whereby said sprocket wheel 33 will, at eachrevolution of the arm 16, be rotated in a direction opposite to thatimparted to it by the finger 32.

In Fig. 7 is illustrated a further modification for shifting the wheelaxle mount during the operation of the machine. At the center of the bedA, I provide a miter rack 34, and gearing with this rack is a miterpinion 35 mounted on a shaft 37 journaled in a bearing 36 depending fromthe arm 16. The shaft- 37 carries a sprocket wheel 3S capable of beingclutched to said shaft by a clutch sleeve 3S) splined on shaft 37 andoperated by a lever 40 which is actuated from a compressed air pistonand cylinder 41. The sprocket wheel 3S is connected by a chain 42 to alarger sprocket wheel 43 mounted on a shaft 45 having a worm 46 meshing'with a worm-wheel 47 mounted on a short shaft 48 which passes throughand is mounted in the arm 16. This shaft 4S carries at each end agear-wheel 49 rigidly connected to said shaft, which gear-wheels in turnmesh with rotatable toothed nuts 50 journaled in lugs 52, depending fromthe arm 16, as clearly shown in Fig. S. An adjusting screw 51 projectsthrough each nut 50 and is engaged by internal female screw threads inthe latter, and a plate 54 secured to each lug 52 has lug 55 whichenters a longitudinal groove 56 in the screw.

By admitting air to the cylinder 41 the lever 4() is moved in thedirection of the arrow, causingthe clutch sleeve 39 to engage and carrywith it the sprocket pinion 38 which in turn rotates, through chain 42and wheel 43, the shaft 45 and worm 46, thereby rotating the worm-wheel47, its shaft 48 and the gear wheels 49 secured on the opposite ends ofthe shaft. These gear wheels simultaneously rotate the toothed nuts 50on each side of the arm 16 and cause them to move the adjusting screws51 simultaneously in the same direction and thereby move the arm 10which is between them. As soon as the proper inclination of the wheels17 with respect to the rails has been attained, air from the cylinder 41is released by the operator and the clutch moved to neutral position andthe arm 10 of the Wheel mount remains in its inclined or rotatedposition.

In Fig. 4 is shown a section with the boss 9 rotatably mounted in thebearing S and secured by key 8a to a collar 9a on which is mounted thesaddle 44EL so that the latter will be adjusted simultaneously with thcwheel mount.
